Objective To determine the molecular mechanism of Yuchang granule (YCG) against ulcerative colitis （UC） by network pharmacology-based approach combined with molecular docking. Methods TCMSP and HIT database were utilized to search the active components and potential targets of YCG. The effective targets of UC were obtained by GeneCards, CTD, and DisGeNET databases. Venn Diagram was exploited to receive common targets of YCG and UC. Network maps of the TCM of YCG-active component-common targets were constructed by the Cytoscape software to gain key active components. Protein-protein interaction （PPI） of common targets was constructed by the STRING database obtaining core common targets. The mechanism and therapeutic effects of YCG on UC were explored via gene ontology （GO） and the biological pathway （KEGG） enrichment analyses. Molecular docking technology was carried out to verify the combination of core active components with key common targets. Results 98 active components and 237 potential targets were sieved from YCG, and 1061 effective targets were screened from UC. 94 common targets of YCG and UC were regarded as potential therapeutic targets. Bioinformatics analysis revealed that quercetin, luteolin, β-quebrachol, stigmasterol, and kaempferol may be the potential candidate agents. Tumor necrosis factor （TNF）, serine/threonine-protein kinase （AKT1）, tumor protein p53 （TP53）, interleukin-6 （IL-6） and IL-1β could become potential therapeutic targets. KEGG showed pathways in cancer, AGE-RAGE signaling pathway in diabetic complications, TNF signaling pathway, and IL-17 signaling pathway might play an important role in YCG against UC. Molecular docking results showed that quercetin combined well with TNF, AKT1, and TP53. And stigmasterol did well with AKT1. Conclusion This study comprehensively illustrated the potential candidate agents, potential therapeutic targets, and pathways of YCG against UC. It also illustrated that YCG could act on multiple targets through multi-pathway treating UC.

Objective The study aimed to elucidate the evolution of the syndromes in Traditional Chinese Medicine(TCM)and TCM syndrome elements in different chronic stages of psoriasis vulgaris.Methods A database was constructed using electronic medical records collected from July 2019 to March 2024 from 1,049 patients with psoriasis vulgaris.The study used Sankey diagrams and network association graphs to analyze the evolution of TCM syndromes and their elements in patients at the different stages:initial diagnosis,progressive stage(Week 2-3),progressive stage(Week 4-5),skin lesion improvement stage(Week 6-7),and remission stage.The syndrome elements network was constructed using community detection algorithms,and the association rules between local skin lesion syndrome differentiation and overall syndrome differentiation were displayed using heatmaps.Results(ⅰ)Initial diagnosis.In the syndrome differentiation of local skin lesions,blood heat syndrome was the most common(79.79％);among the disease location of TCM syndrome elements(called"disease location"),liver was the most prevalent(35.62％);and among the pathological factors of TCM syndrome elements(called"pathological factors"),fire(heat)was the most common(75.48％).(ⅱ)Active stage(Week 2-3).In the syndrome differentiation of local skin lesions,blood heat syndrome remained the most prevalent(73.13％);among the disease location,liver was still the most prevalent(31.71％);and among the pathological factors,fire(heat)continued to be the most common(82.11％),while dampness(22.26％)and qi stagnation(8.39％)began to increase.(ⅲ)Active stage(Week 4-5).The syndrome differentiation of local skin lesions was dominated by blood heat syndrome(45.91％)and blood dryness syndrome(37.19％);among disease location,the interior was the most prevalent(15.25％);and among the pathological factors,fire(heat)remained the most common(50.66％),with an increase in yin deficiency(34.26％).(ⅳ)Skin lesion improvement stage(Week 6-7).In the syndrome differentiation of local skin lesions,both blood dryness syndrome(49.44％)and blood stasis syndrome(33.33％)increased;among the disease location,meridians increased most significantly and became the most prevalent(13.44％);and among the pathological factors,blood stasis increased most significantly and became the most prevalent(28.20％).(ⅴ)Remission stage.In the syndrome differentiation of local skin lesions,blood stasis syndrome became the primary(55.69％),while the percentage of blood dryness syndrome decreased(21.16％);meridians(25.71％)and blood stasis(62.34％)remained the most predominant syndrome elements related to disease location or pathological factors.Conclusion The overall pattern of TCM syndromes in psoriasis vulgaris evolved from excess to deficiency.From the initial diagnosis to the active phase(Week 2-3),heat syndrome dominated;during the active phase(Week 4-5),heat syndrome coexisted with damp syndrome or yin deficiency syndrome;changes in the syndrome element network were the most significant during the lesion improvement phase,with blood stasis gradually increasing and peaking during the remission phase.Blood stasis,dampness,and qi stagnation were pervasive throughout psoriasis vulgaris;qi stagnation and blood stasis may be the main elements causing further deterioration and prolonged course of the disease during the active phase in patients.

【Objective】 To investigate cortical thickness changes in the face-head region of the primary motor cortex (PMC) and its effect on survival in amyotrophy lateral sclerosis (ALS) patients. 【Methods】 A retrospective analysis was performed on 105 ALS patients who underwent head MRI scan at the same time. The A4hf (face-head) region of PMC was used as the region of interest (ROI). According to clinical symptoms, patients were divided into two groups: bulbar involvement and non-bulbar involvement. The differences of clinical features and cortical thickness in ROI were analyzed. According to the symptoms of bulbar palsy, physical examination of nervous system and EMG of tongue muscle, the patients with bulbar palsy were divided into lower motor neuron (LMN), upper motor neuron (UMN) and LMN+UMN groups. The differences of bulbar subgroup score and ROI of cortical thickness were analyzed. Age at onset, body mass index, delayed time of diagnosis, bulbar subgroup score, and ROI cortical thickness were included in survival analysis. 【Results】 ① The ROI cortical thickness was significantly lower in bulbar involvement group than non-bulbar involvement group (-0.198±0.87 vs. 0.235±0.95, P=0.017). ② There were no significant differences in the bulbar subgroup scores or cortical thickness of ROI between LMN, UMN and LMN+UMN groups (P>0.05). ③ Survival analysis showed age of onset (HR=3.296, 95% CI:1.63-6.664, P=0.001), delayed time of diagnosis (HR=0.361, 95% CI:0.184-0.705, P=0.003), bulbar subgroup score (HR 0.389, 95% CI:0.174-0.868, P=0.021), and ZRE_ROI cortical thickness (HR=2.309, 95% CI:1.046-5.096, P=0.038) were independent influencing factors of ALS survival. 【Conclusion】 Cortical thickness in A4hf (face-head) region can more objectively reflect UMN signs of region bulbar. In addition to age of onset and delayed time of diagnosis, bulbar subgroup score and cortical thickness of face-head region are also independent influencing factors, and cortical thinning in face-head region is a protective factor for survival of ALS patients.

【Objective】 The involvement of upper motor neuron (UMN) degeneration is crucial to the diagnosis of amyotrophic lateral sclerosis (ALS). This study aimed to determine objective and sensitive UMN degeneration markers for an accurate and early diagnosis. 【Methods】 A total of 108 ALS patients and 90 age- and gender-matched control subjects were recruited from ALS Clinic of The First Affiliated Hospital of Xi’an Jiaotong University. The motor homunculus cortex thickness data in MRI were collected from all the participants. The clinical characteristics and UMN clinical examination of bulbar, cervical, thoracic and lumbosacral regions were collected from the ALS patients. 【Results】 Cortical thickness was significantly thinner in the ALS group than in the control group in bilateral head-face-bulbar and upper-limb areas (P<0.05). The cortical thickness of the global UMN positive group was significantly thinner than that of control groups in bilateral head-face-bulbar and upper-limb areas (P<0.05). The cortical thickness of the UMN positive group in the corresponding region was significantly thinner than that of control groups in bilateral head-face-bulbar and upper-limb areas (P<0.05). 【Conclusion】 The thinning of the motor homunculus cortex can be used as an objective marker of UMN involvement in ALS patients in clinical practice.

Objective:To compare the effects of staged percutaneous coronary intervention(PCI)after emergency PCI and emergency culprit-only PCI on clinical outcomes of elderly patients with ST-segment elevation myocardial infarction(STEMI)and multivessel disease.Methods:A retrospective analysis was performed on 389 elderly patients with STEMI and multivessel lesions, aged ≥70 years and within 12 h of onset, admitted to the Clinical College of Thoracic Medicine, Tianjin Medical University, between January 2014 and September 2019.According to different revascularization strategies, enrolled patients were divided into the culprit-only PCI group(79.18%, 308)and the staged PCI group(20.82%, 81). Kaplan-Meier analysis and the Cox proportional hazards regression model were used to compare the incidences of major adverse cardiac and cerebrovascular events(MACCE), all-cause death, cardiac death, recurrent myocardial infarction, stroke and ischemia-driven revascularization between the two groups and to evaluate the effects of different revascularization strategies on MACCE and all-cause death.Then subgroup analysis was performed.Results:During a 56-month follow-up, 131 patients developed MACCE and 96 patients died.Compared with the culprit-only PCI group, the staged PCI group had a lower risk of MACCE( HR: 0.404, 95% CI: 0.227-0.716, P=0.002), all-cause death( HR: 0.354, 95% CI: 0.171-0.730, P=0.005), cardiac death( HR: 0.363, 95% CI: 0.157-0.838, P=0.018), and recurrent myocardial infarction( HR: 0.229, 95% CI: 0.055-0.953, P=0.043). There was no significant difference in the incidence of stroke or ischemia-driven revascularization between the two groups( P>0.05). The reduced risk with staged PCI for MACCE and for all-cause mortality persisted in all subgroups.Multivariate Cox proportional hazards regression revealed that, after adjusting for confounding factors, staged PCI was an independent protective factor for MACCE( HR: 0.44, 95% CI: 0.239-0.815, P=0.009)and for all-cause death( HR: 0.390, 95% CI: 0.90, P=0.020). Conclusion:Compared with culprit-only PCI, staged PCI can significantly improve the long-term prognosis of elderly patients ≥70 years with STEMI and multivessel disease within 12 h of onset.
